Can you enumerate your criteria for differentiating "fake" gems from
"real" gems?

This may not be true in 1.9.3, but my trunk installation certainly has
gem specifications for stdlib gems:

[aaron@higgins ruby (probes)]$ gem list psych

*** LOCAL GEMS ***

psych (1.2.2)
[aaron@higgins ruby (probes)]$ gem spec psych | head -10
--- !ruby/object:Gem::Specification
name: psych
version: !ruby/object:Gem::Version
  version: 1.2.2
  prerelease:=20
  segments:
  - 1
  - 2
  - 2
platform: ruby
[aaron@higgins ruby (probes)]$

I'm also able to use `bundle package`:

[aaron@higgins omg]$ bundle package
Fetching source index for http://rubygems.org/
Using psych (1.2.2)=20
Using bundler (1.0.22)=20
Your bundle is complete! Use `bundle show [gemname]` to see where a bundled=
 gem is installed.
Updating .gem files in vendor/cache
  * psych-1.2.2.gem
[aaron@higgins omg]$ cat Gemfile
source 'http://rubygems.org'

gem 'psych', '=3D 1.2.2'
[aaron@higgins omg]$

Can you be more specific about the issues you're encountering?  Thanks!
